Herein, we report an iridium-catalyzed asymmetric hydrogenation of hydantoin and thiazolidinedione derived exocyclic alkenes using our developed BiphPHOX as a ligand. The transformation shows good functional group tolerance, and gives the hydrogenated products with excellent yields (up to 99%) and enantioselectivities (up to 98% ee). A gram-scale reaction was also carried out, and provided the hydrogenated
在此,我们报告了使用我们开发的 BiphPHOX 作为配体的乙内酰脲和噻唑烷二酮衍生的环外烯烃的铱催化不对称氢化。该转化表现出良好的官能团耐受性,并以优异的收率(高达 99%)和对映选择性(高达 98% ee)得到氢化产物。还进行了克级反应,并以优异的收率提供了氢化产物,而对映选择性没有受到侵蚀。最后,氢化产物的转化为合成HIV蛋白酶抑制剂的中间体提供了一种有效的途径。
